3,000 Years ago, I was a demon and you were a human. But you died trying to save me
3,000 years later, I will have the opportunity to cultivate to a positive state. Let me retreat from the demon body, transform into a human being, and marry you as my wife.
But I can only stay with you for 300 days. After 300 days, I will say goodbye.
In the days I spend with you, I hope you fall in love with me, but I don't want you to fall in love with me.
Because I hope you won't be so sad when parting
